li sa 说:谢谢,那和uart是不是挺像,会不会收到bootme?
对了,前两天我那个寄存器写不了,无法改变状态,我使MDCTLn的31置1就解决了。
Table 8-24. PSC1 Module Control n Register (MDCTLn) Field DescriptionsBit Field Value Description
31 FORCE Force enable. This bit forces the module state programmed in the NEXT bit in the module control 15
register (MDCTL15), ignoring and bypassing all the clock stop request handshakes managed by the
PSC to change the state of the clocks to the module.
Note: It is not recommended to use the FORCE bit to disable the module clock, unless specified.
0 Force is disabled.
1 Force is enabled.
感谢分享解决方法。
i2c slave mode会不会发送bootme,这个要去看ROM里的bootloader源码了。
